- Calc-sinter
Calc-sinter (; it is an important category in German chemistry)
Term for a solid
Calcium carbonate deposit. WhenCalcium bicarbonate is in water solution, any mayor change of environmental conditions for the water (esp. pressure, temperature, photosynthesis of biotic material, earthquake) causes the water to release part of itsCarbon dioxide as gas, much like fizzy drinks. As a result, calcium carbonate has been precipitated chemically.When deposits are found in caves, in old aquaeducts or waterpipes - as a coating or even thick layer - this may be called calc sinter. If the deposits are more or less porous - as found behind cold, warm or hot springs - the phenomenon is known as
